Tcos@ = mg
Tsin@ = ÏƒQ/2Îµ

so dividing, tan@ = ÏƒQ2Îµmg

i.e. Ïƒ is directly prop. to tan@

Thanks Ashish..., but wen we apply 2nd equation, then dont we get proportionality with sin theta????

Thats the mistake I made...Plz clarify that...Thanks

Plz clarify my doubt

brother T is itself a variable u have to eliminate it.
